I found this tweak over made by XxXPachaXxX at XDA: The tutorial at THIS LINK shows you how to run the Sony Bravia Engine on your phones.T][ENG.DEV.] Sony Bravia Engine -DHD- HQ IMAGE/MOVIE Quality Improvements - xda-developers
This supposedly works for 2.2, so I tried it. I'm currently on SGM b2.1 on Yonip Final 3D rev04 24bpp, and luckily, my Spica still booted up after the mandatory reboot at the end of the installation, and seems to work fine 20 minutes afterwards..
FEEDBACK: I don't know if it's placebo, but Images became sharper, videos smoother, and scrolling in homescreens, app drawer (GoLauncher Ex btw), and scrolling images via Quickpic became smoother.
Anyone else tried it? They say it doesn't work, but I do feel a slight difference.
I have not tried using the zips there; just used manual installation, and do not forget:
Please do a full backup before trying out, and I am not responsible for whatever damage it may cause.
